import Icon from "@site/src/components/icon";

[Bundles](/components-bundle-components) contain custom components that support specific third-party integrations with Langflow.

This page describes the components that are available in the **CometAPI** bundle.

For more information about CometAPI features and functionality used by CometAPI components, see the [CometAPI documentation](https://www.cometapi.com/).

## CometAPI text generation

This component generates text using CometAPI's language models through the CometAPI OpenAI-compatible endpoints.

It can output either a **Model Response** ([`Message`](/data-types#message)) or a **Language Model** ([`LanguageModel`](/data-types#languagemodel)).

Use the **Language Model** output when you want to use a CometAPI model as the LLM for another LLM-driven component, such as an **Agent** or **Smart Transform** component.

For more information, see [Language model components](/components-models).

### CometAPI parameters

import PartialParams from '@site/docs/_partial-hidden-params.mdx';

<PartialParams />

| Name | Type | Description |
|------|------|-------------|
| api_key | SecretString | Input parameter. Your CometAPI API Key for authentication. |
| model_name | String | Input parameter. The id of the CometAPI model to use. The component automatically fetches the latest available models from CometAPI when you provide a valid API key. For information about supported models, see the [CometAPI documentation](https://www.cometapi.com/). |
| input_value | String | Input parameter. The input text to send to the model. |
| system_message | String | Input parameter. A system message that helps set the behavior of the assistant. |
| max_tokens | Integer | Input parameter. The maximum number of tokens to generate. Set to 0 for unlimited tokens. |
| temperature | Float | Input parameter. Controls randomness in the output. Range: [0.0, 1.0]. Default: 0.1. |
| seed | Integer | Input parameter. The seed controls the reproducibility of the job (advanced). |
| model_kwargs | Dict | Input parameter. Additional keyword arguments to pass to the model (advanced). |
| json_mode | Boolean | Input parameter. If True, it will output JSON regardless of passing a schema (advanced). |
| stream | Boolean | Input parameter. Whether to stream the response. Default: false. |
| output_parser | OutputParser | Input parameter. The parser to use to parse the output of the model (advanced). |
| model | LanguageModel | Output parameter. An instance of ChatOpenAI configured with CometAPI parameters. |

## Use CometAPI in a flow

1. Sign up for a [CometAPI account](https://www.cometapi.com/).
2. Obtain your API key from the CometAPI dashboard.
3. In Langflow, add the **CometAPI** component to your flow.
4. Enter your API key in the **CometAPI API Key** field.
5. Select your preferred model from the **Model Name** menu.
6. Configure other parameters as needed for your use case.
7. Add other components to your flow as needed.

    To perform a basic test, add **Chat Input** and **Chat Output** components to your flow, connect them to the **CometAPI** component accordingly, and then click **Playground** to test the connection and chat with your model.

    For more advanced use cases, you can connect the CometAPI component to other components like **Prompt Template**, **Agent**, or **Smart Transform** components.
